I have had some funny results from TDA. Sometimes the chart shows WMIH style prices. Sometimes the chart shows COOP style prices. My account value shows the appropriate numbers though.
I think yesterdays close in WMIH was 1.31 Multiply by 12 should give an equivalent COOP value of 15.72
So at 16.325 (price as I write this) up .515 from 15.72 - everything seems to check out.
